SUPPORT FOR SHADE-HOLDERS.

To all whom it may concern:

Be it known that I, TRISTRAM GLANDING, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Supports for Shade-Holders, of which the following is a specification.

The invention relates to shade-holders for lamps, and more particularly to means for separably joining such shade-holders to incandescent electric light sockets, and the object of the invention is to provide a yielding collar for such holders, constructed to inclose and automatically grasp such socket; and a further object is to provide simple, inexpensive means for reinforcing such collar and insuring sufiicient spring grasp on the socket to maintain the holder in reliable engagement therewith. 1

The invention consists in certain details of construction and arrangement of parts by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure 1 is a front elevation showing a shade-holder constructed in accordance with the invention, mounted on a vertically arranged lamp-socket.

Fig. 2 is corresponding side elevation of the collar and portions of the attached standards alone.

Fig. 3 is a vertical section corresponding to Fig. 2, taken on the line 33 in such figure, and partly in elevation.

Fig. 4: is a horizontal section through the collar and standards, and partly in plan View. The plane of section is indicated by the line 44 in Fig. 1.

Similar letters of reference indicate the same parts in all the figures.

A A are the standards of a shade-holder carrying at their upper ends a ring B shaped to receive and support a lamp-shade of any desired form and material, not shown. The lower ends of the standards are fastened as by being soldered, in a vertical position to the exterior of a cylindrical collar C on opposite sides thereof. The collar is divided vertically as at 0 to permit it to yield and be forcibly expanded and to contract by its inherent resiliency when released.

The collar is preferably of brass or analogous material having the desired spring quality and its stiffness is increased by a bead C on its lower edge, formed by folding the thin metal upon itself; the upper end is contracted as at C to form an annular internal offset or shoulder adapted to lie upon the usual bead M of an incandescent electric lamp socket M, and locate the collar in proper position relatively thereto.

D is a partial annulus of heavy spring wire, partially encircling the collar C immediately above the bead C and held in place by solder. The spring D is set to exert its force in the direction to contract the collar and reinforce the latter in its effort to close the gap 0 in grasping the socket M.

Thus constructed the collar may be forcibly expanded by increasing the gap 0 in applying the holder upon the socket M, and when thus placed will be held reliably in position by the yieldin grip of the collar, stiffened by the bead g1 and further reinforced by the spring D.

The improved holder is simple in construction and operation and eminently efficient in service. It may be economically manufactured, and by its use the necessity for screws and expensive holding means is avoided.

Importance is attached to the fact that the spring D be arranged adjacent the bead C and that it be applied exteriorly of the collar C so that the spring will bear against the adjacent ends of the standards A and be confined between the same and the said bead. It is also important that the spring be disposed at the end opposite and removed from the end of the collar that embraces the bead on the socket so as to insure more positive frictional hold on the socket at separated points. Although the holder is shown as arranged vertically upon a vertical socket, it will be understood that it may be arranged to serve in a suspended position or to be projected horizontally.

I claim 1. A shade-holder comprising a yielding open collar adapted to inclose and grasp a lamp-socket and be supported thereon, standards secured to said collar, said collar having a bead at one end, and a spring in the form of an open annulus arranged upon the exterior of said collar and disposed between said bead and the adjacent ends of said standards.

2. A shade-holder comprising a yielding open collar adapted to inclose and grasp a lamp socket and be supported thereon, standards secured to said collar, said collar 5 having a bead at one end, and a spring in the form of an open annulus arranged upon the exterior of said collar and disposed between said bead and the adjacent ends of said standards, the opposite end of said collar contracted to form an internal offset to 10 engage a bead on a lamp-socket.

In'testimony that I claim the invention above set forth I aflix my signature in presence of two witnesses.
